Specification of Letters Patent.
Patented May 1915.
appiieation mea april i4, 1914. serial No. 331,782.
To all whom 'it may concern: l
Be it known that I,- FRANCIs V. PHILLIPS, a citizen of the United States, residing at Orlando, in.the county of Orange, State of Florida, have invented certain new anduseful Improvements in Shock-Absorbers for do hereby declare the foland exact descripas will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to shock absorbers for vehicles and particularly for automolowing to be a full, clear,
The object provision of a shock absorber which relies solely upon the element of friction to eiliciently dampen or deaden the action of the springs of a vehicle' and vparticularly an automobile when said springs are violently compressed and rebound.
A A further object of the invention resides 'in the provision of a shock absorber ofthe character named which embodies an improved construction w'hereby same may be rendered inactive upon either compression or rebounding of the springs, inactive upon and active upon both compression and rebounding.
A still further object of the invention resides in the provision of a shock absorber in which controlled and varied and which embodies an improved and simple means for connect-v ing saine to the springs of a vehicle or automobile so that'J the device will always be held in correct relation to the associated spring.
With the above and other objects in view the invention consists in the details of construction and in the arrangement and combination of parts to be hereinafter more fully described and particularly pointed out in the appended claims.
In describing the inventionin detail reference will be had to the accompanying drawings wherein like characters of reference denote correspondingparts in the several views, and in which;
Figure 1 1s a view in elevation showing the improved shock-absorber associated with an automobile spring of the elliptical type;
Fig. `2, a vertical section throughv the absorber on an enlarged scale; Fig. 3, a section on the line 3-3 of Fig 2; Fig. 4, a section on the line 4-4 of ig. 1: on ,an enlarged scale; Fig. 5, a section on the line 'vertical longitudinal section vform of the shock absorber,
of the invention resides in the the friction may be readily and easily the connection between theshoclr;
amodified lower sections 10 and 11 'an The improved absorber is shown as comprising a pair of spaced body'b ocks 13 and 14 connected together by side p 16 through the Vmedium of rive ably mounted between the adj acnt edges of the blocks 13 and-14 is a frictio piston 18. Suitable packing 19 is provided etween the blocks 13 and 14 at each end of prevent the entrance `of dust a the space between said blocks.
d dirt into he face of the block 14 adjacent the block 1 is recessed as at 20 and vseated in this rece' is a ber block 21 bearing against thepis on 18 and adapted to be adjusted .to comensate 'for wear through the mediufri of screws 22 mounted in the block 14. The ace of the block 13 adjacent the' block 14 i provided with a recess 23 in which is slidab y mounted a plate24 having secured thereto a fiber friction shoe 25 bearing against the piston 1 8. The rearl wall of the recess 23 i provided with recesses 26 and 27 the inn rends of which are enlarged "as at 28 and 29 respectively. A passage 30 connects *he recesses 26 and 27 and mounted in this passage is a spring 31 which bears at its erids against rollers 32 and 33 disposed in thelrecesses 26 and 27 respectively and extending transversely ofthe block 13, said rollers Vin turn bearing against the plate 24. Mounted' in.
the enlarged inner ends 28 and 29 of the re-` and respectively, said sprin s bein disposed in opposition to each, ot er an having corresponding arms positioned to enga ge respective rollers 32 and 33. The arms of the springs 34 and 35 remote from the rollers 32 and 33 are engagedl `by screws 36 respectively which are mounted in the block 13 and whereby the tension ofthe springs 34 and 35 may lbe adjusted as will be obvious.
Pivoted to the plates 15 and 16 and block 13 cesses 26 and 27 are V-shapedleaf springs i i on opposite sidesiof said bloclr'through the medium of a bolt 37 are" armsA 38 andv39. Pivoted to the plates 15 and 16 and block 14 on opposite sides of the block 14 through the medium of a bolt 14 are arms 40 and' 4l. A link 42 has one end pivotally connected With the arms 38 and 39 through the medium of the bolt 43, While the other end of said link is pivotally connected with the piston 18 through the medium of a bolt 44. A link 45 has one end pivotally connectedwith the arms 40'andu41 through the medium ofa bolt y 46 while the'other endof said link is pivotally `connected to the piston 18 through the medium df .a bolt 47. f
Inorderfto secure the ends of the. y arms 38 and 39 remote: from the bolt 37 to the section l() of the spring A there. is0 provided aclamp consisting of plates 48 and 49 disposed on oppositesides yofthe sections l0 and connected together by means of bolts'50 and 51 whichserve to draw the into clamping relation to the spring section 10. If desired a rubber packing 52 may be placed between the plates 48 and 49and the spring section l0 but this is not essential. The plate 49 is provided with a hook extension 53 which is engaged over .the clip 12 and serves to secure the clamp formed by the plates 48 and .49,and bolts 50 and 51 against any movement `Whatever on the spring seetion 10. The bolt 50 is provided with an extension 54 u on which is pivotally secured the ends of thcarms 38 and 39 remote from thebolt 37.` The ends of the arms 40 and 41 remote from the bolt 14 are pivotally connected to thespring section 1l in precisely the same manneras the arms 38 and 39 are connected to the rsection 10 and a detail description of such connection will therefore be omitted.
In the operation of the absorber it will be apparent that when the spring'A is violently compressed the arms 38an`d 39 and the arms 40 and 4l will move toward eachother and as a result of the link connections between these arms and the piston :l8'the latter will move longitudinally toward the ends et' said arms connected with the spring A. During this movement of the piston 18 the plate 24 and irictionvshoe 25 will be. drawn along with the piston as will also the roller 33. As the roller 33 moves it will engage the adjacent arm of thc spring35 andthe tension of this spring operating the roller 33 will force the friction shoe 25-into engagement with the piston 18 with constantly increasing strength and result in aconstaii't increase-in the friction' between the shoe and piston so as to dcaden the compression of the spring. As the spring rebounds the piston 'I8 will move iu the opposite direction when the i'oller 32, spring 34. and friction shoe 35 will operate i-ii the manner just described to dea den the rebound of the spring A.
plates .48 and 4.49 f
`roller 60 mounted inv springs 57 and 59 are sov arranged that the it desired to deaden only the compressionof the springA thefscrew 36 is operated spring 34 will exert 32. If it is de rebound of the outwardly so that the no tension uponithe roller sired to' deaden only the 'spring A then the'spring 34'is tensionedfand the screw 36 operated to release the tension of the spring 35. f To render the device entirely inactive the tension of both oltjthe i springs 34 and 35 is released.y By yadjusting the screw 36 itwi'll be obvioust'hat thefrietion present ,between the piston 18 vand the shoe`25 can be readily varied to suit desired conditions.
In the modified form illustratedl Iin i friction shoes 55 and 56 are arrangedonop-1 1v posite Asides ofthe piston 18, the former beupon compression 'l ingforced into engagementwith thepistonf,y ofthe spring through' thel i mounted in they block 13, while the latter is v through the medium of la-spring 59yand n orced .into engagement with` the piston? shoe 55 vis active during the coinprcssion'of .il
the spring, while the shoe 56'is active during in rige -rebound of the spring. In this construction only one V-shaped spring 61 and coperatie-* ing roller 62 is employed, same beingsoar# ranged as to be rendered active when the piston 18 is moved under the influence 'of the. f
rebound of the spring with which the devi/ce'A 'p l.
